Rachel is giving a music lesson out of her home to a new student. She is explaining the use of the metronome to him when she seemingly becomes captivated by its rhythmic ticking. She watches it go back and forth, then lets out a little chuckle as her arms fall limp at her sides. In a sleepy voice, she explains that this always seems to happen to her. Then Rachel’s mind is completely gone. Her will now belongs entirely to her student. She follows his every command without question, remaining in a trance the whole time.
